The Answer is The student had a hordeolum or stye in his right eye. The usual cause is a staphylococcal infection of the eyelash follicle, the sebaceous gland of Zeis, or the ciliary gland of Moll. The suppurative infection tends to point on the anterior part of the lid margin. Repeated multiple styes tend to occur as the result of spread of infection along the eyelid margin.
